is when your teacher walks out of the classroom to go to the common room and has spent a lot of time there, or better still you're sat down and they haven't even turned up yet and then they walk in....every time this happens my heart sinks. Just seeing their knowledge ridden faces *shudder*.

I will contribute my own experience of bad teachers, who turn up around 3 seconds before the cut-off time, after which a class may go home if the teacher is not there. They just loved disappointing us..
